Comment

When I browse this website, if I have AdGuard enabled, these four JavaScript files - jquery-3.6.0.min.js, sweetalert211.js, all.js, app.js - take 2 seconds to load, resulting in slow webpage loading. However, if I disable AdGuard, the loading time drops to below 500ms. I would like to know the reason for this. Username: @s89091189

@s89091189 Hello!

Could you please check if: 1) Disabling DNS module helps. In case it solves the problem we recommend changing Blocking mode for adblock-style rules to Custom IP address. This is most likely the case and it will be fixed in the near future. 2) Disabling Stealth Mode helps

Let us know how it goes, thanks.

I'm disabling DNS module and Stealth Mode, but I don't think it's helping

(Sorry I use a translator)

@s89091189 sorry for delay, could you please send your logs with DNS and Stealth modules disabled.

Also, grab the logs from net-export:

1. Open Chrome browser > type in the address bar: `chrome://net-export` > press Enter. 2. Ensure that Include raw bytes is checked and click Start Logging to Disk. 3. Save the file on the local system. Now, the logging has started. 4. Reproduce the issue. 5. Go back to the Chrome-net-export logging window and click Stop Logging. 6. Find the file in the browser by clicking on Show file and send it to qa@adguard.com​.

@s89091189 any news?

[s89091189]

I apologize for the late reply. I have sent the logs, but I just noticed that the latency has decreased to 600 ms when AdGuard is enabled and 50 ms when it is disabled.
